    • A vehicle compass system that is adapted to be calibrated in the assembly plant during final assembly of the vehicle. In particular, two factory calibration modes are disclosed: an automatic factory calibration mode wherein the calibration sequence is automatically initiated upon the occurrence of a uniquely definable event on the assembly line, and a manual factor calibration mode wherein a calibration button sequence is actuated at a specified location on the assembly line. In addition, an automatic adaptive calibration process is disclosed which continuously updates the calibration constants each time valid new heading data is obtained. In particular, heading vectors for the four main N, S, E, and W heading directions are calculated and stored in memory when the system is initially calibrated. Thereafter, whenever new heading direction data is obtained, the value of the new heading vector is used to update the value of the closest of the four main heading vectors. A new center calculation is also performed using the updated values and if the result is outside a tolerance window, the calibration constants are changed accordingly.
    • 车辆罗盘系统,其适于在车辆的最终组装期间在组装工厂中校准。 特别地,公开了两种工厂校准模式:自动工厂校准模式,其中校准序列在装配线上发生唯一可定义事件时自动启动,以及手动因子校准模式,其中校准按钮序列在 装配线上的指定位置。 此外,公开了一种自动自适应校准过程,其在每次获得有效的新航向数据时不断地更新校准常数。 特别地,当系统初始校准时,计算四个主要N,S,E和W方向的航向向量并将其存储在存储器中。 此后,当获得新的航向方向数据时,使用新的航向向量的值来更新四个主航向矢量中最接近的值。 还使用更新的值执行新的中心计算,并且如果结果在公差窗口之外,则相应地改变校准常数。

    • A remotely actuated solenoid latch apparatus adapted for use in motor vehicle applications is disclosed. The solenoid latch apparatus includes a solenoid having an armature movable between a first position displaced from a pole piece to define a working air gap therebetween to a second position attracted toward the pole piece. A solenoid winding encircles the pole piece and the armature for attracting the armature toward the pole piece upon energization thereof. A latch member is associated with the movable armature for lockingly engaging a striker bar when the armature is in one position and releasably disengaging the striker bar when the armature is in the other position. The present invention is self-compensating to align the latch member relative to the striker bar, prior to engagement therewith, to compensate for alignment variation between the latch member and the striker bar. The pole piece is movable to provide a relatively constant air gap upon alignment of the latch member relative to the striker bar when the armature is displaced from the pole piece.
    • 公开了一种适用于汽车应用的远程驱动的电磁锁定装置。 螺线管闩锁装置包括螺线管,螺线管具有可在从极片移位的第一位置之间移动的衔铁,以在其间限定工作气隙到吸引到极靴的第二位置。 电磁线圈绕圈包围极片和电枢,用于在电枢通电时将电枢吸引到极片。 当电枢处于一个位置时,闩锁构件与可动电枢相关联,用于在衔铁处于另一位置时可释放地使撞针杆脱开。 本发明是自补偿的,以在与其接合之前相对于撞击杆对准闩锁构件,以补偿闩锁构件和撞杆之间的对准变化。 当电枢从极片移位时,极片可移动以提供相对恒定的空气间隙,当锁定构件相对于撞针杆对准时。

    • A tone generator for producing an audible sound for a predetermined time period in response to the occurrence of one or more predetermined conditions. The tone generator comprises a diaphragm mounted within a resonant sound cavity that is activated by an electromagnetic assembly which is in turn driven by the output signal from an oscillator circuit. The control logic and timing circuit for the tone generator includes a unique PTC subassembly that provides a timed logic signal for controlling the activations of the diaphragm, as well as an independently generated signal for contemporaneously activating a lamp which provides a visual indication of the detected predetermined condition. The control logic and timing circuit is adapted to produce the proper timed logic signal despite the absence of a lamp in the circuit or a lamp failure.
